Relationships Between the Usage of Televisions, Computers, and Mobile Phones and the Quality of Sleep in a Chinese Population: Community-Based Cross-Sectional Study.

BACKGROUND: No study has comprehensively investigated the association between the usage of typical screen-based electronic media devices and sleep quality in a Chinese population with individuals in a wide range of ages. OBJECTIVE: This study aimed to understand the characteristics of television (TV) viewing, computer usage, and mobile phone usage in a representative Chinese population in Macau and to examine their roles in predicting the variations in sleep quality. METHODS: This cross-sectional study was an analysis of 1500 Macau residents aged 15 to 90 years based on a community-based health needs assessment study entitled, "Healthy Living, Longer Lives." Data collection was conducted in 7 districts of Macau from 2017 to 2018 through face-to-face interviews. The durations of daily TV viewing, computer usage, and mobile phone usage were recorded in a self-administered questionnaire. The Chinese version of the Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality. RESULTS: The prevalence of TV, computer, and mobile phone usage was 78.4% (1176/1500), 51.6% (769/1490), and 85.5% (1276/1492), respectively. The average daily hours of usage were 1.75 (1.62), 1.53 (2.26), and 2.85 (2.47) hours, respectively. Females spent more time watching TV (P=.03) and using mobile phones (P=.02) and less time on the computer (P=.04) as compared to males. Older adults were more likely to watch TV while young people spent more time using the computer and mobile phones (P for all trends<.001). The mean PSQI global score was 4.79 (2.80) among the participants. Females exhibited significantly higher PSQI scores than males (5.04 vs 4.49, respectively; P<.001). No linear association was observed between the PSQI score and the amount of time spent on the 3 electronic devices (P=.58 for PSQI-TV, P=.05 for PSQI-computer, and P=.52 for PSQI-mobile phone). Curve estimation showed significant quadratic curvilinear associations in PSQI-TV (P=.003) and PSQI-computer (P<.001) among all the participants and in PSQI-mobile phone among youths (age, 15-24 years; P=.04). After adjustment of the gender, age, body mass index, demographics, and lifestyle factors, more than 3 hours of TV viewing and 4 hours of computer usage or mobile phone usage was associated with 85% (95% CI 1.04-1.87; P=.008), 72% (95% CI 1.01-2.92; P=.045), and 53% (95% CI 1.06-2.22; P=.03) greater odds of having poor sleep quality (PSQI score>5), respectively. CONCLUSIONS: The mobile phone was the most popular screen-based electronic device used in the Macau population, especially among young people. "J" shape associations were observed between sleep quality and the duration of TV viewing, computer usage, and mobile phone usage, indicating that the extreme use of screen-based electronic devices predicted poorer sleep status, whereas moderate use would be acceptable.

Sleep disturbance and its relationship with quality of life in older Chinese adults living in nursing homes.

PURPOSE: To examine sleep disturbances in older adults in Macau and Guangzhou, China and their associated factors. DESIGN AND METHODS: Four-hundred and thirty seven subjects in Guangzhou and 244 subjects in Macau were interviewed. FINDINGS: In total, 681 older adults participated in the study, and 27.8% reported sleep disturbance, with 43.9% in Macau and 18.8% in Guangzhou. Physical quality of life was negatively associated with sleep disturbances. Severe depressive symptoms were positively related but living in Guangzhou was negatively related to sleep disturbances. Sleep disturbances are more common in Macau compared to Guangzhou. PRACTICE IMPLICATIONS: Appropriate screening and treatment strategies are needed to address sleep disturbance in this population.

Effectiveness of Acupuncture on Pain, Physical Function and Health-Related Quality of Life in Patients with Rheumatoid Arthritis: A Systematic Review of Quantitative Evidence.

OBJECTIVE: To identify and synthesize the most recent available evidence of effectiveness of acupuncture on pain, physical function and health-related quality of life (HRQoL) in patients with rheumatoid arthritis (RA). METHODS: A comprehensive search of 12 Western and Chinese databases was undertaken from their inception up to end of 2016. Randomized controlled trials (RCTs), concerning patients with RA treated with needle acupuncture, written in English, Portuguese, German or Chinese were included. Primary outcomes included pain, physical function and HRQoL. Secondary outcomes included morning stiffness, functional impairment, number of tender and swollen joints and serum concentrations of inflamatory markers. Methodological quality was assessed by three independent reviewers using the standardized critical appraisal instrument from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. RESULTS: Twenty-two studies met the inclusion criteria. Of those, 9 studies were excluded after assessment of their methodological quality. The remaining 13 original RCTs included 974 patients. Ten of these studies published in China, showed favorable statistical significant effects of acupuncture in relieving symptoms of RA compared with controls. CONCLUSIONS: Evidence suggests that acupuncture interventions may have a positive effect in pain relief, physical function and HRQoL in RA patients. However, due to the heterogeneity and methodologic limitations of the studies included in this systematic review, evidence is not strong enough to produce a best practice guideline.

Elder abuse and its impact on quality of life in nursing homes in China.

There are limited available data on elder abuse and its impact on quality of life (QOL) in China. This study investigated the prevalence of elder abuse in nursing homes and its associated demographic, clinical factors and QOL in Macau and Guangzhou, China. A total of 681 subjects (244 in Macau and 437 in Guangzhou) were consecutively recruited. The prevalence of elder abuse was 11.48% and 8.24% in Macau and Guangzhou, respectively. Multivariate analyses revealed that having a religion and depressive symptoms were independently and positively associated with elder abuse. No significant association between elder abuse and any QOL domain was found. Elder abuse is common in nursing homes in both Macau and Guangzhou. Appropriate strategies and educational programs should be developed for health professionals to reduce the risk of elder abuse.

Clinical characteristics and quality of life of older adults with cognitive impairment in Macao.

BACKGROUND: Little is known about the characteristics of older adults with cognitive impairment in Macao. This study aimed to determine the prevalence of cognitive impairment and the quality of life (QOL) of older adults living in the community and nursing homes. METHODS: A consecutive sample of 413 subjects (199 from the community; 214 from nursing homes) was recruited and interviewed using standardized instruments. Cognition was measured with the Repeatable Battery for the Assessment of Neuropsychological Status and QOL with the brief version of the World Health Organization Quality of Life instrument. RESULTS: Altogether 87 subjects (21.0%) had cognitive impairment. On multivariate analyses, advanced age (P < 0.001, OR = 1.06, 95%CI: 1.03-1.1) and depressive symptoms (P = 0.03, OR = 1.07, 95%CI: 0.005-1.1) were positively associated with cognitive impairment. Married marital status (P = 0.01, OR = 0.3, 95%CI: 0.1-0.7) and higher education level (P < 0.001, OR = 0.1, 95%CI: 0.06-0.3) were negatively associated with cognitive impairment. After the confounders were controlled for, cognitive impairment was significantly associated with the lower psychological (F (11,412) = 6.3, P = 0.01) and social relationship domains of QOL (F (11,412) = 4.0, P = 0.04). CONCLUSION: Cognitive impairment was found to be common in community-dwelling and nursing home resident older adults in Macao. Given cognitive impairment's negative impact on QOL, appropriate strategies should be implemented to improve access to treatment in this population.

Prevalence of Sleep Disturbances and Their Associations With Demographic and Clinical Characteristics and Quality of Life in Older Adults in Macao.

PURPOSE: To examine the prevalence of sleep disturbances (difficulty initiating sleep [DIS], difficulty maintaining sleep [DMS], and early morning awakening [EMA]), their socio-demographic and clinical correlates, and quality of life (QOL) in older adults in Macao. DESIGN AND METHODS: Four hundred fifty-one subjects were interviewed using standardized instruments. FINDINGS: The prevalence of at least one type of sleep disturbance was 38.1%; the figures of DIS, DMS, and EMA were 18.6, 31.3, and 23.9%, respectively. Female sex and depressive symptoms were independently associated with more frequent sleep disturbances. Sleep disturbances were independently associated with lower physical QOL. PRACTICE IMPLICATIONS: Sleep disturbances are common in older adults in Macao. Appropriate strategies should be implemented to prevent and treat sleep disturbances and concerted attempts should be made to improve access to treatment.

Quality of life and clinical correlates in older adults living in the community and in nursing homes in Macao.

AIM: There have been no previous studies of quality of life (QOL) in older adults in Macao. This study aimed to examine QOL in relation to the sociodemographic and clinical characteristics of adults aged ≥50 years in Macao. METHODS: A sample of 451 subjects (203 living in the community, 248 living in nursing homes) was interviewed using standardized instruments. Basic sociodemographic and clinical data including QOL were collected. RESULT: There were no significant differences between the community and nursing home groups in any of the QOL domains. Multiple linear regression analyses revealed that poor physical QOL was significantly predicted by severe depressive symptoms, insomnia, major medical conditions, unmarried status, and lower education ( F 11,438 = 26.2, P < 0.001), which accounted for 38.2% of the variance. Poor psychological QOL was significantly predicted by severe depressive symptoms and lower educational level ( F 11,438 = 24.3, P < 0.001), which accounted for 36.4% of the variance. Poor social QOL was significantly predicted by severe depressive symptoms, male gender, and unmarried status ( F 11,438 = 5.6, P < 0.001), which accounted for 12.5% of the variance. Poor environment QOL was significantly predicted by lower educational level, severe depressive symptoms, and younger age ( F 11,438 = 6.6, P < 0.001), which accounted for 12.1% of the variance. CONCLUSION: Older Macanese adults had poorer scores on physical and social QOL domains than the general Hong Kong Chinese population. Their QOL was more strongly related to severe depressive symptoms, major medical conditions, and insomnia.
